<Begin nitpick>
That's a fun trailer, but a little incoherent. One minute they are fighting in a forest, then they are in a clearing. Are there two factions or three? Is that dinosaur rider on the same side as the faerie women or not? Compositionally, the humans are shown traveling from left to right at first, then they are travelling leftward and the enemy rightward. Then a new group comes straight at the viewer, reinforcing the impression of three factions, but we don't see them actually fighting the humans or the first enemy.. It's a bit of a muddle.
